Which volcanic risk increases following a lava dome collapse?

💡 Explanation

Lava dome collapse can trigger lahars because it releases debris and unstable material that mixes with water and flows downhill as devastating mudflows; therefore, greater debris volumes raises lahar risk, rather than decreasing it or creating volcanic fog (vog).
